I have created a page that is supposed to load up several images through a
movieclip.

I have buttons inside a mc that serve as a drop-down menu. At the release of
the buttons, the main timeline is targeted and in comes up the image.

What's the problem? Well, this function works when I test it locally, so I
know there is nothing wrong with the code. However, after uploading it to my
testing server, it does not work. Even after refreshing my browser and
clearing all the cache files.

Has anyone ever had this problem before?? Any help with this would be
appreciated.

have you checked the permissions for the pictures?

Sometimes if files don't have the correct permissions they won't load.

Cheers,
Gorka
